[Pomoc] undefined symbol "sscanf"

Skripta koju koristim:moju
Detaljan opis problema: ubacio sam dio u skriptu da mogu skinove mijenjat i to slijedeci :

 CMD:setskin(playerid, params[])
{
    new name, targetname, id, skinid, string;
    if(sscanf(params, "ui", id, skinid)) return SendClientMessage(playerid, -1, "USAGE: /setskin ");
    GetPlayerName(playerid, name, MAX_PLAYER_NAME);
    GetPlayerName(id, targetname, MAX_PLAYER_NAME);
    if(id == INVALID_PLAYER_ID) return SendClientMessage(playerid, -1, "Player not connected!");
    SetPlayerSkin(id, skinid);
    format(string, 128, "RCON Admin %s(%d) has set your skinid to %i", name, playerid, skinid);
    SendClientMessage(id, -1, string);
    format(string, 128, "You set %s(%d) skin to skinid %i", targetname, id, skinid);
    SendClientMessage(playerid, -1, string);
    return 1;
}

i onda kada compailam pise mi eror :

D:\dokumenti\desktop\kucni server\gamemodes\invictus.pwn(2040) : error 017: undefined symbol "sscanf"

neki su mi rekli da dodam na vrhu skripte #include ali kada to napisem onda mi server nema niti imena pise unknown , nema spawna niti mapa , nista nema sto sam radio
A ubacio sam btv po uputama one fajlove u plugins , include i u server.cfg mi pise : plugins sscanf

Dio skripte:

CMD:setskin(playerid, params[])
{
    new name, targetname, id, skinid, string;
    if(sscanf(params, "ui", id, skinid)) return SendClientMessage(playerid, -1, "USAGE: /setskin ");
    GetPlayerName(playerid, name, MAX_PLAYER_NAME);
    GetPlayerName(id, targetname, MAX_PLAYER_NAME);
    if(id == INVALID_PLAYER_ID) return SendClientMessage(playerid, -1, "Player not connected!");
    SetPlayerSkin(id, skinid);
    format(string, 128, "RCON Admin %s(%d) has set your skinid to %i", name, playerid, skinid);
    SendClientMessage(id, -1, string);
    format(string, 128, "You set %s(%d) skin to skinid %i", targetname, id, skinid);
    SendClientMessage(playerid, -1, string);
    return 1;
}
